Objects' pertaining to details and economiesf ofmy invention lwill, definitely appear from thedescriptionto follow. Theinvention is defined in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanyingy drawing, in which: c

4ig. 5 is a detail sectionon line 5 5 of Referring to the drawing,k the *housingy in the embodiment illustrated comprises-a boxlike body 1, which is preferably formed as an. integral casting, and a cover 2the operating yparts being mounted within the 4body sov that the. cover .may be removed without disturbing them, y

y Adjacent one end I mount an electric motor3, preferably a variable speedmotor, which is controlled froma lrheostat shown conventionally at 4, the switch being indicated at 5'. The wiring forthe rheostat and switch to themotor is not Villustrated 'as it is believed properV wiring will be understood `by thoseskilledin the art. Y

n The shaft 6 of'themotor is. provided with a pinion-7 which meshes with the teeth of a toothed crank disk 8. Thiscrank disk Sis mounted on astub shaft 9 `projecting from one-fof the side walls of the housing, the

wrist .pin 10.

I mount a rocking or oscillating crosshead- 11 kin a bearing `12 on one of the side walls, the crosshead having a tubular shaftv 13 mounted in a bearing 14 in the opposite wall.. Within this crossheadandforming a part thereof isa rotatable shaftV 15 having screw threads 151 von its outer end. This' screw or'shaft has a beveled gear 16 on its inner end meshing with a gear 17 on the, spindle having a fingery lpiece y19 .at its outer endy on the outside of the casing. 'l The pitman 20V is pivotally connectedat 21 to the coupling 22 having threaded engagement with the screw 15. The crosshead is thus connected tothe crank disk 8'. By rotating; the screw the stroke of the crosshead is adjusted.

In front ofthe crosshead I ymounta pair of rockshafts'23 and-24 vwhich'are disposed in alinement and-supported in bearingsain opposite wallsof the housing.v vA second bearing 25 is provided for the `longer `rockshaft 23. The lrockshafts 23 and. 24 have oppositely disposed arms 26S-'and 27, respectively, at their inner ends, andthesearms are connected by the links 28 to the rocker crosshead 11 so that as fthe crosshead is oscillatedjthrough the vconnections 'with the kmotoras described, the rock'shafts'are oscillated in lopposite directions. On ,the outer ends ofthe rocksh'aftsal V mountV the applicator en'gagingarms 29 jprog crankdiskbein'g provided with a crank or :y

applicators as; these may be varied consider'- ably in form'. Suitable applicators are.

shown in the patent to Kellogg andl Goodrich, No.V 1,585,9231dated-May 25, 1926. Y,

Toadapt the machine to-a wider varietyl of. uses, the arms 29- are adjustably secured to thelrockshaft so that they maybe swung to a horizontal' position if desired, orto-a verticalposition,` or in fact, to anyintermediate position. To accomplish this the rockshafts are provided with collars-3 1 having' toothed orL serrated faces 32. The arms 29 havehubs*33.,rotatable on the shaft and having; teeth or serrations 34 coacting with fio lis
